I cleaned and started it back up and it's now heated to about 102. Problem is, now it will peak at that temp and gradually lose heat over the next few days. I believe the reset button trips on the heater also. Could the thermostat be bad again? I replaced it 2 seasons ago.

My tiger river bengal spa will not hold it's heat. I've made sure there is no air in the lines. The temperature and water will heat but only to a certain point.(about 90degrees). It will then slowly lose heat over the course of a couple days. It will not heat back up unless I drain it and start over again. It then goes through the same cycle all over again. I've replaced the pump last year and replaced the thermostat the year before. Is it another thermostat problem? I thought maybe I got a bad one. Any suggestions? Please help!
